The primary aim for this study is to design, develop and analyze of knee implant by using additive manufacturing technique. Recent developments in additive manufacturing give more opportunities in the development and fabrication of surgical implants. Implementation of structural design optimization and additive manufacturing is great way to design and fabricating of lightweight medical implants that biomechanical properties same as original bone. By using topology optimization tried to reduce weight of knee implant. A weight reduction is achieved near about 25% to 30 %. The topological optimized part is fabricated by using 3D printing manufacturing process. For overall analysis stainless steel 316L is used. The prototype of knee implant is made in Poly lactic acid (PLA) material. Comparing finite element analysis results of original designed knee implant with optimized knee implant.
